SPRING-WHEEL.

Specification of Letters Patent.

Patented March 17, 1908.

Application Bled July 6, 1907. Serial No. 382,468.

To all whom 'it may concern:

Be it lnown that I, HENRY E. SCHINDLER, a citizen of the United States,residing at Sisseton, in the ,county of Roberts, State of South Dakota, have invented certain new .and useful Improvements in S ring-Vheels;

. and I do hereb declare the fol owing to be a full, clear, an exact description of the invention, such as will enable others slilled in the art to which it appertains to maire and use the same.

The present invention relates` to improvements in s ring-Wheels, and it aims to provide an e cient and durable device of that nature designed especially for motor vehicles,

` the essential feature of the invention consisting. of a hubyieldingly mounted between the spaced plates which comprise the web of the wheel, whereby the wheel may give when sub'ected to pressure. a e invention further consists in the construction, combination, andV arran ement ofA parts, all as hereinafter more fully escribed,

,specifically claimed, andl illustrated in the .section taken axiall accompanying drawings, 'in which like parts ale designated by4 corresponding reference numerals in the several views. t Of the said drawings-'.-Figure 1 is a front elevation of a wheel constructed in accordance with the present invention. Fig. 2 is a therethrough. Fig. 3 is an enlarged detai view showin the inanner in which the inneren'd of eac spring is fastened'to the hub. Fig. 4 is a section on the line 4 -4 of Fig. 2. Fig. 5 is a 'section on the line 5-5 of Fig. 1.

In Fig. 1, the spring upon the opposite side of the wheel is shown in dotted lines.

In its ractical embodiment, the wheel includes a ollow cylindrical hub 5, having a vertically disposed circumferential 'flange 6 formed thereon intermediate its ends, and a web 7, which latter consists of a pair of annular plates 8, the outer periphe of each plate bein flanged to form part o the felly 9 in Whic -the tire 10 is fitted. Towards their inner peripheries, said plates are bowed pair of spaced ears 12 havin0r alining perforations formed therethrough or the reception of the outer end of a heavy coil-spring 13 which is held in lace at such point by a pair of split pins 14 isposed on opposite sides of one ear and fitted in openings formed through p the spring. The inner end of each spring. ex-

tends through a notch 1 6 formed in the ad- 'acent end of the hub, and terminates Tin a aterally bent portion 17 which thus prevents a direct withdrawal of said end from the hub,

the opposite ends of which latter are closed.

by a pair of threaded plugs 18 and 19 against Whose inner faces the bent portions of the.

spring ends bear. Each plug is provided 'ilo with a polygonal shoulder which projects'r slightly beyond the'corresponding end of the hub, and is adapted to be engaged by a The plu 19 on the IO* Wrench or similar tool. inner side of the Wheel is, in ad ition,

vided with a central opening through W ich the adjacent end 'of the axle of the vehicle extends, the interior of the hub having a race formed therein in vwhich the usual antiffriction bearings are disposed.

The springs 13 above referred to are rie-.`

versely wound with res ect' to each other and the pair of ears forme u on one plate is, in consequence, disposed iametricall opposite that formed upon the other p ate, the notches through which the inner ends of the springs extend having a similar arrangement.

Owing to the fact that the diameter ofthe chamber l1 formed by the web-plates is considerably greater than that of the hiib'lan e 6 which is fitted therein, the web is capabgle of an independent movement bodilyfwith respect to the hub and axle of the wheel, whereby the latter will yield when the vehicle is traveling over a rough road, thus coiiperatd ing with and assisting the ,springs proper with which the vehicle is provided. The life of the tire which is attached to the felly of the l wheel is likewise materially increased by reaf son of the yielding mounting of the wheel.

What is clainie is,

A wheel comprising a web portion consisting of a .pair of' annular plates secured together, said lates having their outer peripheries flanged) to form a felly, and their inner peripheries bowed outwardly in opposite directions to form an internal chamber; a' hollow cylindricahhub `yieldingly mounted with respect to said web and provided With'a circumferential flange disposed within said Chamber, ea-oh end of Said huh being interthe notch in the adjacent @nd 0f the hub into nelly threaded and provided with a notch; a the interior thereof. threaded plug fitted in each end of said huh; and a pair of coil-springs disposed upon opposite sides of said web and revereely Wound with respect to er1-ch other, each spring having one end fastened to the adjacent plate and having its other end extending through In testimony whereof, I aIiX my signature,

in presence of two witnesses.
